Bullfrogs are the largest real frog found in North America, weighing up to 0.5 kg and measuring 460 mm in length. Their average length is 100-175 mm. Their color varies from brownish to shades of green, often with spots or blotches of a darker color around their backs. Their back feet are fully webbed.
It is not assuming too much to affirm that the ladies themselves were hardly so ladylike as Thomas Bullfrog. Bullfrog and I came together as a unit, we took two seats in the stage-coach and began our journey towards my place of business. Bullfrog, repeated she, you must not disarrange my curls. Bullfrog, said my wife, coolly taking the basket from my hands and replacing it on the front seat. Bullfrog alive, nor, though I looked very sharply about the coach, could I detect any traces of that beloved woman's dead body.
